This app isn't in any of our charts yet.
Stopping the fan while a call or alarm has paused it now stays stopped when the interruption ends. Volume no longer doubles after a notification or navigation prompt. The app opens straight to its screen even without a network connection. Play and purchase errors are shown instead of a button that does nothing.
Real box fan sounds that play all night, plus a sleep timer. One button.
Simple sleep does one thing: it plays the steady sound of a real box fan until you wake up. No sound libraries to scroll through. No subscription. No ads. Open the app, tap play, and go to sleep. - A real fan recording, looped so smoothly you can't find the seam - Set a stop time — the sound fades out gently before it ends, so it never wakes you - Keeps playing with the screen off, all night — best left on a charger - Volume and stop time are remembered for tomorrow night - Works completely offline Try it free for 24 hours. If it helps you sleep, unlock it forever for $0.99 — one time, not a subscription. That's the whole business model: you pay once, you own it, and no ads ever appear.
